To allwhpm-tt may concern:

ful Improvements. in Cushioning Devices for Tires, of which the following is a spe'ei fication.- p ThlS. mventiongcompr'ehends certa n new and.,u seful improvements incushioning de-' v ces forthe', .tires of wheelsof automobiles orI-other vehiclesgenerally, and for other purposes, and, the primary object. of the in volition-is an {improved cushioning means whichwill, inthe present embodiment of the invention herein illustrated, produce. an efiicien t and resilient wheel, Without the use of the ordinary pneumatic or cushionrubber tires, without requiring-the usev of rubber-'0r steel springs to secure the desired re iliencn.

The invention, consists essentially in a cushipning'device embodying a plurality of bands,'str1ps or layers of some pliable and.

substantially inelastic and non-stretchable fabric, and a series of rigid 'supports'ar ran edin predetermined spaced relationto eac other and interposed between the bands, the supports being secured to the hands so ast prevent a creeping or. circum-v ferential movement oithe supports relative to. the bands as well as any lateral displacement, the parts. being so arranged that a .blow or. stress imposed in a radial direction at anypoint. on the cushioning device, will cause a dip in the bands at the point where,

- theblow or-stressoccurs, the same being resisted by the entire set of supports and bands,and the supportsvmoving toward the pointy where the dip or impress occurs and taking up such impress one after the other to a gradually decreasing degree. in opposite directions away from the point of stress, so as to secure the proper reflex actionland produce the desiredresiliency.

The invention also consists in a cushion ing device embodying a plurality of pliable bends, supports interposed between said bands and secured thereto and tensioning devices arranged to tension the bands in a specification of Letters raten'tr PatentedJa n, 10,1911

which the tensioning devices are omitted;

Figs. 5 and 6 are transverse section-alviews illustrating other modifications herein spe-. cifically referred to.

Corresponding and like-parts are referred to in the following description. and-indicated in all the views of the accompanying 95 drawing by the same reference characters. In carrying out my. invention,.I employ a,

' relatively strong, to1igh,and pliable-material or substance, possessing if, possiblesome elasticity when under stress. For exampleJ may '100 hide, gut, strong-cord, rope, twme, o'rj'r1b' bone or use leathensteelwire', steel rope, canvas, rawbandsmade of these materials. or

idliibiiiatibns thereof, J01 :fwit-h combination with, relatively "I bits .P which are preferably entirely of material, although I they may embody, more or $1 5 rubber or some resilient material-as IY be m n d actual practice- In the drawing,' 1 designates the rim of the vehicle wheel in which, for the purpose of illustration only, I have shown my invention ',stood that the supports?! are connecte'd to. the strips 2 by any desired means which will as embodied, the said rim or-felly, as well asthe interior parts of the'wheel such asthc spokes and hub, being of I any desired con? stru'ction, design or type.

In that'embodim nt ofgthe invention as Illustrated in- Fig. 1, the"iiumeral 2 desig of the supports; that may be formed of any desired substance or material, or composition or combinations thereof, either solider tubular, the said supports being interposed between the innerand outer strips 2, and being spaced from each other, preferably at equi-' distant points, and in any desiredpred'termined spaced relation. It is to be undersubstantially prevent. any, circumferential movement-10f thesupportsfl relative to the strips,' ziswe=lli=as any lateral displacement.- For instance, for the purpose of showing-one .rneans that may be employed, I have indicated that the supports 3 are secured to the; outer band or strip 2 by rivets or'pins 4' in! dicated; in dotted lines. 5 designates lugswhich are arranged to permit a swaying-or. rocking of the supports. I It is to be understood that my invention is not limited to; any'particular mechanical element for' accomplishing the desired result or; connection just mentioned. Any of the sup ports may be rounded as indicated at'6 so as to permit the supports to rock or turn when a'stress is imposed on that portion of the band or bands between them.

-It is'-manifes't that under some circumstances'at least, it will be advantageous to provide some way of increasing or decreasing the tension imposed upon the strips, bands or layers 2. -As one means for accomplishing this end, reference is to be further had to Fig. 1, wherein tension screws? are shown as working through threaded apertures inthe felly 1 engaging at their outer- Q ends or impinging upon the innermost set of supports designated 3* which, so far 'as their function is concerned, are substantially. like the supports 3, thead-j'ustable tensioning feature being not 'now considered. It is of course, also to be understood that the sup-- ports 3 like the supports 3, are held against any appreciable circumferential movement relative to the bands or strips as well as the wheel rim, it being noted that the. supports .3! are I secured "to the band" of Which-e11? fcircles them',- as -by a rivet or pin 4,. o'r any' 2, any desiredfnum'ber of, strips may; be use other desired means, and that they are held in; relative stationary relationv to the wheel 'rim or felly1=1as bythe blocks S-pairs of fli' 1s it limited to the use ofthe. tensioningdevices 7. j For example,- as best scent-in F four being there illustrated.

If, for 'iex ample,l a blow, stress, or impression ofany character be imposed inan mwar'dly radiai direction .upon the cushioning devices, say

" at the point indicated by the arrow X,-fi. t is. I evident that the pliable stri s, bandsjor layers. 2, will dip inwardly,-su stantially as illustrated by the dotted: line 3 'g this;in ward stress causing" the adjoining supports to move inwardly or :in -a' circumferential direction with" their adjoining portions of thestripsfrom all sides, fromthe oint upon which the stress has been impose the inward movement of the outermost strip, band or layerbeing resisted by all portions thereof, together wit-lithe supports, aswell as the innerlying strips and supports, and the desired resiliency being thereby 'eii'ectually produced. v 2

Fig. 3 illustrates substantially the arrangement of parts. already ilescrib'ed'whe'n referring to Fig. 1, except that in order to compensate for the weakening effect which would otherwise be produced upon the'felly tion of which thestrips,

.improved cushioning devices,

it -is to be understood that In not confined to theuse of strips ofleather,

' laid in strips .of-definite width, but I may mentary inwardly extending flanges 13 seessary to employ plurality the outer envelop or canvas, or equivalent materials or substances which may be formed either'by a of convolutions of asinglew1re, rope, cord, cable. or'the' like, or that the bands or layers maybe formedby a series of relatively independent and distinct rings laid side by side in any desired transversely spaced relation, orin close contactwith each use bands .otheraccording 'as judgment may, dictate.

In the latter event-,that is where a plurality ofindependent rings are used, whether the rings themselves be formed of-wires, bands,

cables or the like as before mentioned, or of gpliable strips of any desiredv width, it is clear that eventhough .one strip, ringor the like should break or-become in any wise impaired, the entire structure would not be thereby endangered asto its'usefulness, for

the remaining bands orlayers would still remain inta ct.-

The whole tire or. cushioning devices may also'be inclosed'by an outer cover or shoe. of substantially circular shape. n cross sec-- t1on,. as ndicated 40 at 10, in Fig.5 or of any desired "shape or connection with single or double tube pneumatictires, and 'as further illustrated in this I view,

the rim such as the ,channeled rim there shown,-m ay be. conveniently constructed {of any-of the accepted; types to facilitate the mounting or takingofi of the shoeli' 'Or, as illustrated in Fig. 6, the flangesoram nulaz-ll ofany suitable material may be sjecured at both sides of the felly 1. and the outer. rim may be provided with supplecuredthereto' in any desired way.

. From the foregoing description in connection with the accompanyingsdrawings, it is obvious that'I have provided a very simple, durable and efiicient construction of cushioning meansior vehicle wheelsfor for other purposes, generally, in which, to obtain the desired elasticity or. resiliency, it is not'necf springs,'wi thin the accepted meaning of this term, my improved cushioning devices de-' pending, to secure the desired result-,- upon anovel and useful arrangement of 'p strips, bands ,or layers,
